A new method for assessing the interpersonal behavior of psychopathic individuals: Preliminary validation studies.

Abstract

Two studies examined whether increased attention to interpersonal behaviors would improve assessments of the personality core underlying psychopathy. After item analysis, 21 items measuring interpersonal interactions and nonverbal behaviors associated with psychopathy were retained as the Interpersonal Measure of Psychopathy (IM-P). Federal prison inmates (Study 1, N *= 98) and undergraduates (Study 2, N ~ 92) were rated on occurrence of these behaviors during an interview conducted to complete either Hare's Psychopathy Checklist-Revised (PCL-R) or Psychopathy Checklist: Screening Version (PCL: SV). In both studies, IM-P scores correlated more highly with PCL Factor 1 than with PCL Factor 2 scores. Regression analyses indicated that, after controlling for demographic variables and PCL factor scores, IM-P scores predicted interviewer emotional responses and participants' adult fighting (Study 1) and ratings of participants' interpersonal dominance (Study 2 ). Thus, measurement of interpersonal behavior appears to permit improved prediction of several criteria linked to the personality core of psychopathy.

Initial development of an implicit and explicit approach to assess psychopathy

“…Cooke et al, 2004;Hare, 1991Hare, , 1997Kosson et al, 1997;Levenson et al, 1995;Lilienfeld & Andrews, 1996;Lynam et al, 2011;Patrick, 2010). Focus has been on the development of explicit measures with few (e.g.…”

“…Furthermore, it was positioned as the exemplary model for the evaluation of psychopathy and as a parameter for validation of new scales (Kosson, Steuerwald, Forth, & Kirkhart, 1997). This influence is so great that few studies on the subject, after the year 2000, do not involve an instrument of the PCL family.…”

Psychopathy: A Behavioral Systems Approach

“…Each of these reflects ingratiating or relatively "prosocial" dominance strategies. IM-P total scores correlate significantly with PCL-R total, Factor 1, and Factor 2 [68][69][70]. IM-P total scores also correlate with IASR-B5 observer-rated and self-rated dominance [68,70].…”

“…IM-P total scores correlate significantly with PCL-R total, Factor 1, and Factor 2 [68][69][70]. IM-P total scores also correlate with IASR-B5 observer-rated and self-rated dominance [68,70]. Due to dominant interpersonal behavior, psychopathy maps into quadrant 2 of interpersonal circumplex space as assessed by both observational (CIRCLE) and self-report measures (IAS, IASR-B5 and IIP).…”

“…The Interpersonal Measure of Psychopathy developed by Kosson and colleagues [68] assesses, alliance seeking, expressed narcissism, showmanship and the degree to which the subject incorporates the interviewer into stories. Each of these reflects ingratiating or relatively "prosocial" dominance strategies.…”
